2r + 6
Step-by-step explanation:
have a good day :)

- a number

- its square

- the sum

- less than or equal
negative three - I don't have to explain this one, do I?

- the sum of a number and its square is less than or equal negative three
We know that
step 1
if ∡YWZ=17°
then
∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents
step 2
∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents
we know that
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2
∡WXY=[180-34°]/2-------> ∡WXY=73°
the answer is
∡WXY=73°
It is finding the closest estimate to number. Rounding is used in everyday calculations and in many different fields of work
